Result indicates a fraction , Guan Cheng number increasing by makes occupy first place over second ketones to increase by, the Guan Cheng number occupies first place over second ketone mole of fraction effect especially under low rate of flow of low temperature is lower situation, with regard to comparatively obvious; Feed rate increasing by, uses A second ketones mole of fraction go down , the feed rate is anxious to outdo others to a certain extent under the low temperature to A second ketones mole of fraction effect in the temperature to A second ketones mole of fraction effect; But occupy first place over second ketones mole of fraction with the temperature power-up but rise, the too high temperature (above 200 ~C) meeting makes subsidiary outcome increase by , affects reactor effect; The experiment Er Yan , the temperature choosing are 200 ~C , the Guan Cheng number is 3 to, the feed rate is that F = carries out reaction about 5 ml/h is comparatively rational.
